Abstract:

The quilting process involves stitching two or more layers of fabrics to produce a thicker material, typically to make heat-insulating products. In addition to stitching, ultrasonic quilting is increasingly used. Quilted multi-layered textile materials are widely used in outerwear, especially in autumn and winter conditions. The aim of the work was to analyse the impact of the quilting process on the thermal insulation properties of multilayer textile packages. Three-layer packages were quilted using different quilting parameters. Then, the thermal protection properties of the packages were tested before and after subsequent quilting steps. Alambeta and Permetest instruments were used to test the thermal insulation properties of the packages. Based on the research performed and statistical analysis of the results obtained, it was found that quilting has a significant impact on the properties affecting the heat protection of multi-layer textile packages. Thermal conductivity, thermal resistance and thermal absorptivity depend on the number of quilting seams, stitch type and thread thickness used for quilting. Generally, quilting causes a decrease in the thermal resistance of multi-layer packages of textile materials.
